the sum of the first n terms of a sequence is 20 - 10 / 2 ^ n - 1 find the sum of the first five terms

Travka [436]

Answer:

$S_5=\dfrac{170}{9}$

Step-by-step explanation:

Given that,

The sum of first n term of a sequence is $S_n=20-\dfrac{10}{2n-1}$

We need to find the sum of the first 5 terms.

Put n = 5,

$S_5=20-\dfrac{10}{2(5)-1}\\\\=20-\dfrac{10}{10-1}\\\\=20-\dfrac{10}{9}\\\\=\dfrac{170}{9}$

So, the sum of first 5 terms is equal to $\dfrac{170}{9}$ .

Solve for x X - 1/2 (8 - x) = x + 3(4 - x) - x<br> A) -32/9<br> B) -9/32<br> C) 32/9<br> D) 9/32

Greeley [361]

Option C

$x = \frac{32}{9}$

<em><u>Solution:</u></em>

$x - \frac{1}{2} \times (8 - x) = x + 3(4 - x) - x$

We have to solve for "x"

From given,

$x - \frac{1}{2} \times (8 - x) = x + 3(4 - x) - x$

Solve for brackets

Use distributive property

a(b + c) = ab + ac

Therefore,

$x - 4 + \frac{x}{2} = x + 12 - 3x - x$

Combine the constants

$x + \frac{x}{2} = x - x - 3x + 12 + 4\\\\x + \frac{x}{2} = -3x + 16$

Move the variables to left side of equation

$x + \frac{x}{2} + 3x = 16$

Combine the like terms

$2x + x + 6x = 32\\\\9x = 32\\\\x = \frac{32}{9}$

Thus option C is correct
